' TOLEDO, OHIO. A CORPORATION OF NEW JERSEY.

- ELECTRIC-CHECK-PRIN TIN G SCALE.

Application .filed November 7'0 all whom it ma concern;

Beit known that I, SAMUTEI'. G. CRANE, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio,haveinvented certainnew and useful Improvements inEIectric-Check-PrintingScales, of which the following is a'specification.

This invention relates to weighing scales, to automatic check printingscales. While inventions of scales of this type have heretofore beenmade, it is believed that no practical scale has hereto fore beendevised which will automatically issue a printed check of the unknownweight of the commodity being .wveiglned without the aid of a manualoperation.

The principal object of this invention is to' provide a scale which willautomatically determine the weight, print the same upon a check, andissue the check by means entirely within the scale itself, the onlyoperation efi'ected by the operator being the placing of the commodity'upon the platform. Thus in stores and shops where commodities ofunknown "weight are continually being placed upon the scale platter myimproved scale is particnlarly'adapted, and also in factories whereparts of machinery and the like must be accurately measured by the weiht thereof, as when erated in 0011- I nection with a conveyor of anyfamiliar type, and the successive commodities may be weighed and printedrecords of the weight issued in rapid succession without the as sistanceor attendance of a weight checking clerk. It will be obvious that thescale is also adapted for many and various types of weighings. V

Another object of my invention is to provide a novel mechanism for sotiming the operation of the printing mechanism that said mechanismwillnot be actuated until after the weighing operation iscompleted andthe weighing parts of the scale are at rest.

With the above and other objects in view which will readily appear asthe invention is better understood, my invention consists in the novelconstruction, combination and a rrangcment of parts to be hereinaftermore fullv described and particularly pointed out in the appendedclaims.

Reference is to be had to the accompany-- 21 1919. Serial No. s39.as.

\Vhile my invention is adaptable to many different styles and makes ofscales, whether the load-offsetting device therein be spring, lever orpendulum, the present embodiment is adapted forv use in connection withdial scales where an indicating hand is adapted to swing over a'graduated chart to 'indi-.

cate the weight weighed. In the of 1 the commodity being drawings, "ldesignates the usual scale housing mountediipon flCOltlIflD 2 whichconnects with the base'and platform levers (not shown). 'As the(weighing or loadoffsetting mechanism of the scale forms no part of thepresent invention, I will de scribe it briefly, the mechanism beingpreferably of the type adapted to weigh comparatively heavy loads. Thependulum connform the pendulums will be swung upward-f;

ly into a position coun'terbalancing the weight of the load on the platfornntbe penclnlums falling again to their normal or zero position whenthe load is removed from the scale platform. Asherein shown, thependulum counterbalance mechanism comprises a pair ofoppositely-disposed pendulums 5, each of which comprises supportingseg-' ments 6 secured on transverse. shafts, and the I two shafts areconnected by crossbars 7 the,

segments 6 being suspended from the lower izcr bar ll.

ends of flexible supporting ribbons secured at their upper ends upon theframework of the scale. Intermediate the supporting segments of eachpendulum isa somewhat larger segment 8, which is also fixed to thetransverse shaft, said segment extend ing at its periphery between thepillars of the framework supporting the segments (5, and being connectedto the upper'cnd, as at 9. to a flexible metallic ribbon 10 whichextends over the arcuate face of the segment and is attached at itslower end to an cqnal- The construction of the two pcndnlums issubstantially identical. and the ribbons 10 are connected to oppositesides of the equalizer bar 11. which is centrally connected, as by thelink 12, with the upper end of the steelyard rod 4, which. as beforedescribed, is connected with the lever 3.

In the operation of the scale, when a load is placed on the scaleplatform. a downward pull is exerted on the equalizer bar ll, which istransmitted through the ribbons 10 to the larger segments 8. causing aswinging of'the pendulums 5 so that the pendulum weights are raised to ac'ounter balanced position. During the winging movementv of thependulums to afset the weight of the load, the crossbars 7 a ,e movedvertically upward,- and through the medium of this vertical movement ofthe crossom's the weight indication on the dial is effected;- theerossbars 7 carrying a vertically disposed rack upon the indicator shaft15 carrying the index hand 16. The indicator shaft 15 is mountedconcentrically of the dial 17 having the desired weight raduationssuitably inscribed thereon, as, or example. in the manner illustrated inFi 1, with which graduations the index han 16 co-operates in indicatingthe weight of the load being weighed. "1 his pendulum counterbalancemechanism is sufficient to independently offset the weight of all loadswithin the capacity shown on the dial.

Supported within the column 2 and 00- operating with the scale beampivoted therein is a timing switch mechanism, which, as will be apparentfrom the following descrip tion, comprises one of the important featuresof this invention. A resilient member 19 is .securely fastened to oneside of the-column land extends across the upper portion thereof. itbeing suitably shaped so as to provide an elongated opening surroundingportions of the scale mechanism extending through the column, such asthe sleelyard rod con necting the platform levers with the beam '3, etc.Mounted upon the free end of the resilient member 19 is a dash pot 20,the lower portion of which extends through an opening in the bracket 18,thereby permit- 13 meshing with a pinion 14 fixed Gil ting the dash potto swing with this resilient member. Limiting means are preferablyprovided to prevent undue swinging movement of the dash pot andresilient member, as herein shown comprising adjusting screws 21 mountedin the member 19 adjacent the dash pot and adapted to contact thebracket- 18 when the limit. of the downward movement of the dash pot hasbeen reached. A plurality of L-shaped guides 22 are adjustably mountedupon the column 2, the short arms of which are adapted to extend over 1the edge of the member 19 and limit the upward movement thereof. Securedwithin the column 2 and above the resilient member are brackets 23 inwhich is journalled a transverse rock-shaft 24 having needle point orother suitable anti-friction bearings and carrying a crank arm25'whiclris pivotally connected to the resilient member 19 by the link26, and a crank arm 27 of much greater length than the arm 25 andextending in the opposite direction, the outer extremity of whichoperates between the shorter arms of upper and lower contact levers 28and 29 respectively fnlcrumed between the vertical arms of a standard30. The extremities of the longer arms of the contactlevers 28 and 29are adapted to engage the upper and lower contact screws 31- and32carried by but insulated frornthe bracket 18. The upper. lever. 28 hasits -shforter arm operatively connected with a timing device 33, thepurpose of which will appear inthe following paragraph. The plungerofthe dash pct is operatively connected withthe scale beam 3 by means ofthe plunger rod 20 and serves to damp the vibratory movementsotthedelicate parts of the scale.

Thus, it will'be apparent that whilethe weighing mechanism of the scaleis in opera tion the. scale beam 3 will be caused 'to vibrate, whichwill force the plunger to reciprocate within the oil cylinder of thedash pot. As the dash pot is suspended upon the free end of theresilient member 19, the action of the plunger in the oil will impart avibrating movement to the dash pot switch 44 controlling the rotation ofthe which will causethe shaft 24 to be rocked by reason of the crank arm25 and l nk 26.

The rocking of the shaftl124 causes the free end of the crank arm 27 toalternately en gage the shorter arms of the contact levels 28 and 29,and break the engagement of their longer arms with the contact screws 31and 32. Thus, when the scale beam 3 is pulled downwardly, the dash pot20 is moved correspondingly, causing the free end ofthe arm 27 to moveupwardly and breaking the contact of the upper contact-"lever 28 withthe contact screw 31. The shorter arm ofthis lever, 28 is connected tothe timing device 33 and retards the movement of the lever 28 inresuming its normal position in engagement with the contact screw 31 topermit the current of electricity to flow through the switch set up bythe levers 28- and 29 and the contacts 31 tively.

It ,is obvious that should the previously described switch mechanismalone be used, the circuit would be closed when the scale is at rest.and no load upon-the platform which would cause the printing mechanismto be actuated. In order to overcome this difii culty I provide inaddition to this timing switch mechanism a master switchmechanism whichis adapted to be closed only when a commodity is placed upon theplatform of the scale. the arrangement being such that before theelectrical current can operate the check-printing mechanism, bothswitches tnust be closed. This master switch is normally open andadapted to be closed upon the ownward movement of the steelyard rod 4.This master switch comprises a switch arm 35 mounted upon but insulatedfromthe frame of the scale and is normally held in a raised position bymeans of a lug 36 of insulating material carried by the steelyard rod. Acontact screw 37 is positioned to engage the switch arm 35 when the and32 respecactuated until the completion of the weighing operation andwhich includes means for. rotating the driving mechanism for theprinting disks proportionately to the rotation of'the index hand 16 whenindicating the weight of the commodity on the platform of the scale andmeans for stopping the rotation of said mechanism when the correctarrangement of type numerals is obtained. More specifically, thismechanism comprises a disk 40 fixedly mounted upon the indicat-or shaft15 and having a rearwardly projecting stop arm ilsecnred thereto in anysuitable manner. This rearwardly-project- -in'g arm 40 co-operates witha rotating large driving gear 42, which is mounted with its axis inalignment with the shaft 15 and provided with as many teeth as there arepounds indicated upon the dial 1?. This rotating switch is normallyclosed and is broken when the gear 42 moves through a partial rotationcorresponding to the movement of the index hand showing the weight of aconnnodity on .the scale platform. This switch 44 comprises aninsulating segment block 44' mounted upon a hub 45 of the driving car 42and secured to the gear in any suita le manner. I A pair of spacedcontacts 44 and 44" are secured to the peripheral face of the block 4%,while a flexible switch member4-i is secured to the contact 44 andengages the contact 44", thereby normally keeping the switch closed. Thefree end of the switch member 14 extends a certain distance above thecontact 4-4 in the path of travel of the arm 41. Mounted upon the hub 45in the rear of the gear 42 are a pair of spaced contact rings 46 and 47electrically connected with the contacts 44 and 44" respectively throughwires 46 and 47 (see' Figs. 5 and 9). Brushes 4S and 49 contact therings 46 and 47 respectively. Mounted rearwardly of the rings 46 and 47'is a standard in which is journalled in snit able bearings a shaft 50keyed to the hub 45 and having secured thereon a pair of timing cams 51and 52, the'purposeof which will appear later. Engaging the cam 51 isone end of a switch arm 53, the other end being pivoted to a standard54, said arm normally being in contact with a contact screw 55electrically connected with the switch contact screw 37 of the masterswitch Electrically connected with the standard 54 is a pole-c angingmotor 56 which is provided with a inion secured to the armature thereoffor driving the gear 42. A switch member 63 (see Fig. 8)- similar inconstruction the lower end of a right-angled arm thereof to be out ofengagement with a contact screw 64. Upon rotation of the gear 42the cam52 will be revolved, thereby lowering the arm 63 and permitting theengagement of the right-angled arm with the contact screw 64, therebypermitting the current of electricity to flow to a magnet 65supportedby'the scale framework and in such position that when energized the manet will attract the disk 40, thereby locking theindex hand and drivingmechanism against rotation. (See Fig. 7.)

The, printing disk mechanism may be of any familiar type, the embodimentherein shown being one form particularly adaptable for use in connectionwith the present form of device. WVith particular reference to Figs. 3,18 and 19, I have shown the printing mechanism as consisting of a plurality ofdisks 57 having numerals arranged consecutively on theperipheries thereof and so arranged that upon rotation of the shaft 58upon which the disks 57' are mounted, the numerals will beproport-ionatel moved to indicate successive pounds and ractionsthereof. In order to provide means 1 for such rotation of the disks 57 Ihave shown a pinion 59 secured upon the end of the shaft 58 and in meshwith the driving gear 42', which, as hereinbefore stated, is providedwith teeth in number corresponding to the capacity of the'seale inpounds- Upon the opposite extremity of the shaft'58 I provide a starwheel 60, which, when engaged by th'elatch 61, serves as a stop for theprinting mechanism and serves to align the type numerals for clearprinting. The arm of the latch 61 has one of its ends pivotallyconnected to the base of an electro-magnet 62, while the armaturethereof is in such relation to said arm that when the magnet isenergized the arm will be lifted, thereby permitting the free end to beretracted from engagement with the star wheel. (See Figure 13.)

When a commodity is placed upon the platform of the scale the weighingmechanism is actuated as hereinbefore described to offset the weight ofthe load. As the shaft 15 is rotated, carrying with it the index hand 16to indicate the weight of the load, the disk 40 is'simultaneouslyrotated to position the stop arm 41. During this weighing operation themaster switch 35 is closed but the timing mechanism, including the upperand lower switch levers 28 and 29, which is in circuitv with the switch35 and checkprinting linechanism, is open, thereby preventing theactuation of the driving gear 42 and associated mechanism until theweighing operation is completed and the index to. a. standstill, therebypermitting the tim-*- ing switch to close. The current then flows fromthe service lug S located in the upper part of the scale housing andconnected to a battery B or other 'source of electrical supply to themaster switch 35 (which was closed as' the steelyard rod 4 was pulleddownward to actuate the pendulums), thence to the switch 53 electricallyconnected with the driving motor 56 and to the magnet 62, which liftsthe latch 61 from engagement with the star wheel 60, releasing the 'gearwheel 42 and associated mechanism. The motor 56 drives the large gearwheel 42 and causes the shaft 50 to revolve, and the cam disks 51 and 52which are secured on the shaft'to operate the switch arms 53 and 63respectively. The cam 52 is so timed that upon the beginning of therotation of the gear 42 the switch arm 63" will he lifted, therebyclosing the circuit in the switch which permits the magnet 65 to hecomeenergized, thereby locking the disk 40 and the weighing mechanism of thescale against movement. It will be remembered that the disk 40 carryingwith it the stop. arm 41 has been rotated correspondingly to the indexhand so that the stop arm remains in transverse alignment with theindexhand when indicating the weight of a commodity. When the disk 40 islocked by means of the magnet 65, the lug 41 provides a stationaryrearwardly-extending stop adapted to engage the upper end of theflexible switch member 44 as the switch 44 revolves with gear 42,thereby opening the switch to stop the motor 56 and 'de-energizing themagnet 62, causing the latch 61 to re-eugage the star wheel 60 toprevent movement thereof. As the latch 61 drops back into engagementwith the star wheel 60 under tension of a 5 ring 66, a circuit switch 67is closed, there y energizing a magnet 68, to the armature of which isconnected an arm 69 having formed at the end thereofa hammer adapted toimpinge a paper strip or card upon the type disks when the magnet isenergized. Carried by the arm 69 is a finger 70 adapted to close acircuit switch 71 as the arm is attracted to the magnet 68, therebycausing a magnet 72 to become energized, the armature 73 of which isarranged to actuate a pole-changing device electrically connected to themotor 56 for reversing the rotation thereof, returning the gear wheel 42and associated mechanism to zero position. Simultaneously the armaturecloses a switch for energizing the check-issuing mechanism ashereinafter described.

After the printing operation is effected,

rollers 77 and *78 respectively, geared r ether to cause one of saidrollers to revolve in a direction opposite to that of the other. Keyedto the lower shaft 76 is a pinion 79 in mesh with a verticall disposedrack 80 slidably supported by the racket 7 4 and normally held 1n araised position by yirtue of a rin 80. The lower extremity of the rackar 18 formed as the core of a solenoid 81, which, as will behereinafterfexplained, when energized effects a down- ;ward movement of the rackbar 80. Secured.

to the bracket 74 is a check-cutting member, Dositioned in a planetangentially with the iuncture of the two feeding rollers, andcomprising a "knife member 82-pivotally secured at one end to thebracket 74, while the other end is normall held in a raisedposition byreason of a coiled spri 82'. Referring to Figs. 3 and 12 it will benoted, however, that provision has been made fpr means whereb thesolenoid may be energized until the me bar has completed itsdownwardmovement adapted to engage .a trip member 84 ivoted lb an insulatingmember supported y said bracket 74. A switch lever 85 is pivotallymounted 11 has one on provided with a contact point, preferably ofplatinum, adapted to engage ;a contact screw 86,but normally held out ofengagement therewith by reason of a springpressed plunger 87 engagingthe o posite and longer end of the lever 85. e tri member 84 isconnected to the plunger 8 by means of a piri-in-slot connection and 1'sobvious that as the rack 80 is moved downwardly from its normal position(see FIG 12), even to the slightest degree, the arm 83 will en age thetrip member 84 which will withdraw the plunger 87 from engagement withthe lever 85, thereby rmitting the contact end of the lever, y reason ofa coiled spring 88, to. engage the contact screw 86. Pivotallyii--suported by the insulati member is trip ever 89, one arm of WlllOl'l isin the path of travel of a fi er 90 carried by the upper end of the rackar, and the other end thereof engaing the under side of the longer armof the ever 85. Thus, after the rack has moved its full stroke downward,the fin er 90 engages the end of the trip lever 89 which causes thelonger end of the lever 85 to be raised and retained in that position byto sever the stripgofpaper from roll t'othe rack bar 80 is an 83' n saidinsulating member and means of the plunger 87 to break the circuit forenergizing the solenoid 81 and associated mechanism.

I Suitable means for inking the type may be employed, the embodimentshown herein being su'fiiciently adaptable to facilitate in an eflicientoperation of the machine. As shown in Fig. 13,- a plurality of guiderollers 92 aremounted' upon the framework, and passing around theserollers is an inked ribbon 93 which passes over the type bars and underthe paper strip. Adjusting means such as shown at 94 may be employed toregulate the tension of the ribbon. Secured to one of the rollers is aratchet and pawl 95 adapted to be engaged by a dog 96 carried by thegear wheel 42, whereby the ribbon is slightly moved over the printingdiscs upon every revolution of the gear wheel.

The mechanism for supplying the strip of paper 102 for the ticketscomprises a reel 103 mounted on the scale frame and carrying a roll ofpaper guided over idler rollers 104, thence passing over printing wheels57, between feed rollers 77 and 78, and under the knife '82, whichsevers the strip, the cut and printed ticket being guided by chute 105to receiving pan 106 mounted on the column 2 of the scale.

In order that the operating mechanism may be automatically reset for thenext weighing operation it is necessary to again change the circuits orrather set the polechanging device to its original position. Toaccomplish this inan eflicient manner (see Figs. 3 and a trip lever 97is pivoted to the frame 74 and .normally urged downwardly by a spring97, one end thereof being pivotally connected to the trip 7 3 while theother end engages a latch 98 formed with a shoulder upon which the triplever 97 rests after therotation of the motor has been stopped and thepoles reversed. A dog 100 is keyed to the shaft and as the gearapproaches the zero position of the scale on its return movement the dog100 engages the latch 98 and releases the trip lever, causing the trip73 to rise, changing the poles to the original condition.

VVhile it will be apparent that the illustrated embodiment of myinvention herein disclosed is well calculated to adequately fulfill theobjects and advantages primarily set forthi, it is to be understood thatthe invention is susceptible to variation, modification and changewithout departing from the spirit and sco of the invention as set forthin the subjoined claims. it
